A track grading classification scale has been developed to assist in advising Trip Leaders and participants on 4WD trips of the type of tracks that they can expect to encounter. It is intended, over time, for all 4WD tracks to be rated according to this scale and sign-posted accordingly.

On most 4WD trips participants can expect that a variety of tracks will be traversed each with an appropriate rating. Trip Leaders should advise participants of the range of track ratings expected to be encountered on the planned route.

The following classifications will assist in determining an overall Trip Rating:
